Filed Jan. 1.7, 1931 Patented Oct. 4, 1932 MAGARET MARSHALL, Ol'VANCC'U'VER, BRITISH COLUMBIA, CANADA VACUUM: CLEANER Application illedJanuary V17, 1931. Serial No. 509,485.

This invention relates to improvements in vacuum cleaners and moreparticularly to the lusual fabric dust bag to be found on the majorityof omestic vacuum cleaners.

An object of the improvements is to provide better and incre hygienicmeans for the removal of the dust contents from the cleaner.

Another object of my invention is to preserve the usual fabric dust bagin a more sanitary and cleanly condition than when used as a dustcatcher and holder.

Another particular object of my invention is to provide means fordisinfecting the room in which the vacuum cleaner is being used.

'l5 And a still further object of my invention is to provide a moreexpeditious and cleanly way for the ultimate disposal of the dust con- Itentsof the cleaner.

The invention consists in providlng an auxiliary container designed tofit snugly within the usual fabric dust bag found upon housei holdvocuum cleaners and to receive the dust therein, thereby protecting theouter fabric bag from contamination and dirt.

It is a well known fact that after frequent use the usual fabric dustbag becomes diiiicult to clean and to empty the contents therefrom as,owing to the escape of the air through the fabric, some portions of thefine dust contents are caused to adhere to the inner walls of the bagand these in' time add to the adhesive qualities and cause anaccumulative effect of dust gathering therein, the consequences of whichincrease the unsanitary condition of the fabric dust container.

Another objectionable duty in connection with vacuum cleaners is theremoval of the dustcontents from the bag, which, besides being diiiicultas before mentioned, is a messy job usually entailing the spreading outof newspapers for depositing thereon the dust collected in the bag andthe wrapping up thereof and careful removal.

The above recited difficulties and objections are at once-removed by theuse of my invention.

My invention will be more readily' understood by reference to thedrawing accompanying and forming part of this application, in

fo which Figure 1 is a perspective view of the auxlliary contalner,showing a reinforced neck flange and a fabric valve inside of thecontainer, the disinfectant pocket is shown dotted.

Figure 2 shows the protruding end'of the' auxiliary container beyond thereinforced ends of the fabric dust bag.

Figure 3 shows the protruding end of the auxiliary container folded overthe end of the fabric dust bag.

Figure 4 shows the metal clip member applied over the ends of theauxiliary container and fabric dust bag to secure closure.

Figure 5 is a section taken on the line 5-5 of Figure 1 showing thedisinfectant pocket.

Figure 6 is a-perspective view of the metal clip member used on sometypes of vacuum cleaners to close the end of the dust bag.

In the drawing like numerals indicate To like parts and 7 indicates abag constructed of light, tough paper of a shape adapted to fit into theporous fabric dust bag 12 of 'the vacuum cleaner to which it is to beapplied.

A reinforced neck flange 8 is formed on '.5 one end of the paper bag forsecuring under the clamp of the vacuum cleaner used for attaching thefabric dust bag.

It is desirable to have the paper bag a little longer than the fabricbag, when used with some types of vacuum cleaners, such as the new typeHoover, which makes use of an open ended dust bag closed with a metalclip as it then permits the protruding paper ends shown in Figure 2being folded over the outside seams of the fabric bag, as shown inFigure 3, and being secured by the metal clip 11, as shown in Figure 4:.

In one side of the paper bag I provide an air release to permit theescape of the air therefrom while retaining the ne dust contents withinthe bag.

This air release shown at 9 in Figure 1 consists of a patch of finelymeshed fabric pasted or otherwise secured into the side of the paperbag. It is at this point I provide my disinfecting means by havingformed u on the inner surface of the fabric valve an on the inside ofthe paper bag a pocket to hold a. cake i of solid disinfectant. Thispocket is shown ',100

at 10 in Figure 1 and a sectional view of this pocket is shown in Figure5, and permits of the ready insertion of disinfectant when and asrequired.

It will be noted that the disinfectant p'ositioned in the pocket is inthe path of the escaping air from the paper bag and is, there,-v fore,actively acted upon by the outgoing stream of air.

By this sim le means it is possible to disinfect and purify the air inthe rooms in which the vacuum cleaner is being used and leave themsmelling sweetly wholesome instead of having that musty smell sofrequently found in recently vacuumed rooms. v

After use, it is a simple matter to remov the paper bag by removing theclamp at the lower end and tightly twisting the neck of thepaper bag toprevent the escape of the .dust contents, (care being taken not todestroy the paper flange collar) and then pulling out the paper bagfrombthe open end of the fabric bag after the removal of the metal clip.

A particular advantage is the manner in which the paper bag dischargesall the dust fan box and having its other end secured to thecorresponding end of the fabric dust bag, said auxiliary bag havingawindow opening in its side covered by a fine mesh screen and a pocketof fine mesh fabric secured inside MARGARET MARSHALL.

Having now fully described my invention, what I claim and desire to beprotected in by Letters Patent, is:

l. In a vacuum cleaner having the usual fabric dust bag attached, thecombination comprising an auxiliary containerfitting inside said fabricdust bag, said container having means by which it may be secured in saidfabric dust bag, and having a screened window opening for permitting theair to escape therefrom, and means within the auxiliary containeradjacent the window opening thereof for disinfecting the room in whichthe vacuum cleaner is used.

2. In a vacuum cleaner having the usual fabric dust bag attached, thecombination comprising an auxiliary container iitting inside said fabricdust bag, said container hav? ing mea-ns for securing said fabric dustbag, means for permitting the air to escape therefrom, said meanscomprising an insert of finely meshed fabric on one sideof saidauxiliary container and secured in and across a window opening in thewall thereof, means for disinfecting the room in which the said vacuumcleaner is used, said means comprising a pocket member formed on theinner side of said insert and of similar material to that of saidinsert, and shaped to receive a cake of disinfectant, said pocket beingpositioned in the streamline of said escaping air whereby thedisinfectant is acted upon by said escaping air.
